Heraion of Samos, Ancient sanctuary in Samos, Greece

The Heraion of Samos is an ancient sanctuary in the marshy basin of the Imbrasos river, 6 km southwest of Pythagoreion. Its core is the Temple of Hera, where only one column of the unfinished Polycrates temple still stands, made of stacked cylindrical stone drums in pale beige and grey, with a large piece broken away near the middle. Low stone blocks and a leafy tree stand nearby.

The sanctuary originates from the 8th century BC and underwent multiple construction phases, with its most elaborate form developing during the rule of Polycrates. The site maintained religious importance for local communities across many generations.

The sanctuary held deep meaning for Ionian worshippers, who gathered here to honor the goddess Hera with processions and ritual offerings throughout the year.

The sanctuary lies in the low, marshy basin of the Imbrasos river, about 6 km southwest of Pythagoreion, reached by road from the village. Ground is uneven among the ruins, so wear sturdy shoes and bring sun protection and water. The single standing column of the temple of Polycrates is the landmark to head for.

Excavations revealed a remarkable collection of terracotta offerings, ivory objects, and large stone figures left by worshippers over the centuries. These discoveries demonstrate how wealthy and influential this sanctuary was in the ancient world.
